Abstract

The invention discloses a flavored mashed sweet potato and a processing method thereof. The flavored mashed sweet potato is prepared by processing mashed sweet potato and modified starch, the mass ratio of which is 1-6:1, and further comprises pyrophosphate and fermented rice vinegar which respectively account for 0.1 percent to 0.5 percent and 0.04 percent to 0.3 percent of the gross mass of themashed sweet potato and the modified starch; wherein the mashed sweet potato is made of one or more of purple sweet potato, Chinese sweet potato and sweet potato with red core. The processing method takes the one or more of the purple sweet potato, the Chinese sweet potato and the sweet potato with red core as raw materials and sequentially comprises the processing steps of cleaning, peeling, steam boiling, coarse grinding, mixing, fine grinding, stewing, packaging, pre-cooling, quick freezing, etc. The flavored mashed sweet potato has the advantages of special local flavor, total nutrition, high added-value, convenient eating, easy preservation and the like, and the processing method has the advantages of low cost, simple operation and the like.
